Resurfacing arthroplasty is increasingly used to treat arthrosis of the proximal interphalangeal joint. However, the presence of ankylosis increases the risk of complications; thus, there are few reports on this procedure in the context of ankylosis. The present report describes the case of a 32-year-old man who presented with posttraumatic proximal interphalangeal arthrosis with bony ankylosis in flexion and ulnar flexion. We performed resurfacing arthroplasty and collateral ligament reconstruction to correct ulnar flexion deformity. At 12 months after surgery, joint extension was -40° and flexion improved to 100° with no ulnar flexion deformity recurrence, loosening, or implant failure. Although resurfacing arthroplasty is generally not suitable for ankylosed joints, we obtained excellent results in this case of bony ankylosis of the proximal interphalangeal joint by adjusting the collateral ligament balance appropriately.
表面置换关节成形术越来越多地用于治疗近端指间关节的关节炎。然而，关节强直的存在会增加并发症的风险；因此，关于在关节强直情况下进行该手术的报道很少。本报告描述了一名32岁男性的病例，该患者因创伤后近端指间关节关节炎伴屈曲和尺侧屈曲的骨性强直而就诊。我们进行了表面置换关节成形术和侧副韧带重建以纠正尺侧屈曲畸形。术后12个月，关节伸展度为-40°，屈曲度改善至100°，无尺侧屈曲畸形复发、松动或植入物失败。虽然表面置换关节成形术通常不适用于强直关节，但我们通过适当调整侧副韧带平衡，在该例近端指间关节骨性强直病例中取得了优异的效果。
